Readers can talk about what a book meant to them through reviews and word of mouth, but I doubt it gets back to the author for the most part. One of the frequently cited pieces of advice for writers is to not read your reviews. It's good advice, because reading a negative review can destroy a nascent writer. But it means that authors are left wondering about their translation skills as they change imagination into words.

Unlike most readers, Mark actually gets to close the circle of writer, story, and reader. I've tweeted a few authors and talked to authors in blog post comments, even asked questions at readings. But it's not the same as what Mark does because my interactions never rise above thank you and you're welcome. I love what Mark does because he gets so into the books that I've seen him read. I don't know if I have it in me to respond the way Mark does.
At any rate, Mark, if you ever end up reading this, I salute you. Shine on, you crazy diamond.
